The BCU310 output control signals of the voltage between terminals of group, the voltage between terminals for making set of cells 300 are changed into the output of supply unit 3
Voltage.
Specifically, host controller 7 connects switch S1, the S3 illustrated in Fig. 2 via HCU, and disconnects switch S2, while
Disconnect switch 91,92.So, the battery 330 from set of cells is to capacitor supply electric power, according to the capacity of the capacitor 340
Store electric charge and generate voltage（Such as 300V）.Then, host controller 7 is stored after electric charge in capacitor 340, via
While HCU disconnects switch S1, ON switch S2, S3, thus ON switch 92, disconnection switch 91 enter to DC/DC transducers 34
Row voltage is controlled, so that the output voltage of DC/DC transducers 34（Voltage between the lead-out terminal of transducer 34）It is changed into capacitor 340
Voltage（Such as 300V）.Then, it is changed into identical electricity in the output voltage of DC/DC transducers 34 and the voltage of capacitor 340
After pressure, ON switch 91.
Here, due to carrying out to the output voltage of DC/DC transducers 34 in the case of ON switch 92, disconnection switch 91
Control, therefore the reference voltage of capacitor 340 can be made identical with the reference voltage of DC/DC transducers 34, easily compare electric capacity
The voltage of device 340 and the output voltage of DC/DC transducers 34.Also, by switch S1～S3 for being arranged in set of cells 300,
Chopper 320, capacitor 340 etc., can prevent to the inrush current in battery 300.
Also, for the experimental system used for electric vehicle 100 of present embodiment, by by electricity in motor test pattern
Machine 200 is driven as motor, so as to dynamometer machine 2 be driven as electromotor, will be generated electricity by dynamometer machine 2 accordingly
Regenerated electric power is stored in the Reserve Power Division 33 in supply unit 3（The arrow B of Fig. 1）.Equally, in motor test pattern, pass through
Dynamometer machine 2 is driven as motor, so as to motor 200 be driven as electromotor, accordingly will be by 200, motor
The regenerated electric power of electricity is stored in the Reserve Power Division 33 in supply unit 3（The arrow A of Fig. 1）.Thus, due to trying in motor
Test in pattern produce regenerated electric power store to Reserve Power Division 33, therefore can in motor test circuit L1 circulating energy, can
To realize energy-saving.
According to the pilot system used for electric vehicle 100 of such present embodiment for constituting, turned on by circuit switching part 4
Motor test circuit L1, such that it is able to test performance of motor 200 etc..Also, led by circuit switching part 4
Logical battery set charge/discharge circuit L2, such that it is able to carry out the discharge and recharge of set of cells 300, may be adjusted to desired battery and holds
Amount（SOC）.So, can be tested and for being mounted in EV for the motor 200 for being mounted in EV or HEV by a system
Or the set of cells 300 of HEV carries out discharge and recharge.It is therefore not necessary to prepare the special supply unit of battery set charge/discharge, it is possible to reduce set
While standby cost, installation space can be saved.Additionally, being filled to set of cells 300 with circuit L2 by battery set charge/discharge
Electric discharge, so as to reach desired battery capacity without the need for moving same as before（SOC）Set of cells 300, but by switch to
Set of cells-motor connection circuit L3 and connect set of cells 300 and motor 200, such that it is able to carry out using the electricity of the set of cells 300
The test of machine 200.
Here, the present invention is not limited to above-mentioned embodiment.
For example, the change of the Changing Pattern of the set of cells for representing actual can be stored in the memorizer of power supply controller
Rule program, in electric motor test device, can make to play the supply unit that motor is powered filling as set of cells simulation
The function of putting.Here, Changing Pattern program carries out modeled data by use to set of cells constituting.Power supply is based on controller
The Changing Pattern program, control DC/DC transducers etc..
And, although the common supply unit used in dynamometer machine and motor of the supply unit of above-mentioned embodiment, but
Different supply units can also respectively be used.Now, the power supply for the discharge and recharge of set of cells can use one of those.
In addition, although in the above-described embodiment by switching device control unit controlling switch, but it is also possible to switch circuit
Portion has mechanical switch, and by user's manual switching mechanical switch.
Additionally, in the pilot system used for electric vehicle of above-mentioned embodiment, it is also possible to be configured to carry out set of cells
Charge-discharge characteristic test, cycling life test etc..Specifically, discharge and recharge is stored in battery set charge/discharge controller special
Property test procedure or cycling life test program, and CPU or peripheral equipment cooperation are made according to these programs, so as to be tested.
Also, for each controller of above-mentioned embodiment, each function physically respective split shape can be directed to
Cheng Hou, is communicated by wired or wireless way, it is also possible to make host controller and motor test controller or set of cells
